Load.But after long-time use, door inner panel 2 and the sheet metal component of the junction of back reinforcing plate 1 easily occur due to firm
The generation of solder joint cracking phenomena caused by degree and insufficient strength, so as to cause lock to fail.
Utility model content
The purpose of this utility model is to provide a kind of reinforcement structure of back door lock installation position, it is possible to increase back door it is whole
Body intensity, rigidity, solve the problems, such as metal plate and solder joint cracking.
To achieve these goals, the technical solution adopted in the utility model conduct：A kind of back door lock installation position adds
Strong structure, the plate body at latch position is installed on door inner panel includes the substrate that plate face is in horizontal position on the whole, is offered on substrate
The aperture of arrangement is stretched out for dead bolt, extended downwardly on the outside of the both sides edge in vehicle commander direction on described substrate lower extending plate,
The upper inner panel that inner side upwardly extends, reinforcing plate is provided with described aperture, reinforcing plate is folded plate shape and corresponding plate face and base
Plate, lower extending plate and upper inner panel are bonded and are welded as a whole, and are offered in the main body being bonded in reinforcing plate with baseplate part and aperture phase
The through hole of symbol.
Compared with prior art, reinforcing plate is bonded with three substrate, lower extending plate and upper inner panel plate faces, after greatly strengthen
The bulk strength and rigidity of tailgate metal plate, the probability of metal plate and solder joint cracking is reduced, extend the service life of back door.

Embodiment
The utility model is made with reference to Fig. 3-Fig. 5 discussed in further detail.
A kind of reinforcement structure of back door lock installation position, the plate body at door lock location A is installed on door inner panel 10 includes plate face
It is in the substrate 11 of horizontal position on the whole, offers the aperture 111 that arrangement is stretched out for dead bolt on substrate 11, described substrate 11 is upper
Lower extending plate 12 is extended downwardly on the outside of the both sides edge in vehicle commander direction, the upper inner panel 13 that inner side upwardly extends, described aperture
Reinforcing plate 20 is provided with 111, reinforcing plate 20 is folded plate shape and corresponding plate face is pasted with substrate 11, lower extending plate 12 and upper inner panel 13
Merging is welded as a whole, and the through hole being consistent with aperture 111 is offered with 11 main bodys 21 being bonded of substrate in reinforcing plate 20
211.Lock body B dead bolt passes through from aperture 111 and through hole 211, the bending being made up of substrate 11, lower extending plate 12, upper inner panel 13
Door inner panel 10 can inherently improve the intensity at installation door lock location A, cause to install door lock A positions in order to avoid impulsive force is excessive
The place of putting deforms, so increase reinforcing plate 20 here, reinforcing plate 20 and 13 3 substrate 11, lower extending plate 12 and upper inner panel plates
Face is bonded, and greatly strengthen the bulk strength and rigidity of back door metal plate, is reduced the probability of metal plate and solder joint cracking, is extended
The service life of back door.
Preferably, described reinforcing plate 20 is arranged in the inner side plate face of an inner panel 10, and reinforcing plate 20 is that global sections are in Z
The tabular of type, mounting hole 231 is offered on the installing plate 23 being bonded with upper inner panel 13, the edge of supporting plate 22 being bonded with lower extending plate 12
Overall width direction is provided with coating groove 221, and the notch of coating groove 221 is arranged towards lower extending plate 12.The inner side of so-called door inner panel 10
Or outside should understand as follows：Door inner panel 10 and external door panel form door-plate, door inner panel 10 towards the side of external door panel be inner side, in door
The side that trim panel is mounted with plate 10 is outside.Installing plate 23 is fixedly connected by mounting hole 231 with upper inner panel 13, supporting plate
